Everyone,

I am trying to create external snapshots of a kvm guest machine and have not been able to do so.

In accordance with : https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/htm...

I have used the command line :

snapshot-create-as --diskspec vda,snapshot=external,file=/u4/guest/MaBa- clone/test.snap.img--domain MaBa-clone --name MaBa-clone_snap --description "Snap before 9Aug2020"

This command line gives me the error : error: unsupported configuration: disk 'vda' must use snapshot mode 'internal'

Is it possible to perform an external snapshot of a kvm guest?
